Dear Mr. Dzung Nguyen,
I must thank you for your sense of responsibility, courtesy and your hospitality, which enhance image of your country. I started loving your country and your countrymen.
When I looked into your vietnam history, I am really amazed.
Covey my thanks to your company for having provided an excellent service for my vietnam tour.
I have not given anything great as a quantity of business. But, You respected me and encouraged me to come back again to Vietnam, when I first time could not enter into your country.
I would always remember you and looking forward to your visit to India.
Thanks a lot.
